New Maps Show The Path Of Neanderthals’ Huge Migration Across Eurasia
Between 120,000 and 60,000 years ago, Neanderthals embarked on a second wave of major migrations from Eastern Europe to southern Siberia and Central Asia. Using supercomputers, anthropologists have now managed to track the path of that journey…

Photometric Analysis of Asteroids in the Phocaea Region
Asteroids with similar orbits, i.e., proper semimajor axes, eccentricities, and inclinations, can constitute a dynamical family. Such families, also called asteroid families, are thought to have their origins in catastrophic collisions of larger…

Adaptive Weighted Multi-image Shape from Shading for Precise Topographic Reconstruction at the Lunar South Pole
The generation and analysis of fine surface topography are critical for landing site selection at the lunar south pole. The Shape from Shading (SFS) technique can theoretically reconstruct a pixel-level resolution topographic model. However,…

TESS Investigation—Demographics of Young Exoplanets (TI-DYE). III. An Inner Super-Earth in TOI 2076
Young (<500 Myr) multiplanet transiting systems are valuable environments for understanding planet evolution by offering an opportunity to make direct comparisons between planets from the same formation conditions. TOI 2076 is known to harbor…

Determining the Methanol Deuteration in the Disk Around V883 Orionis with Laboratory Measured Spectroscopy
Deuterium fractionation, as studied through mono-deuterated methanol, is frequently used as a diagnostic tool to trace the physical conditions and chemical evolution of interstellar sources. This study investigates methanol deuteration in the…

The True Stellar Obliquity of a Sub-Saturn Planet from the Tierras Observatory and the Keck Planet Finder
We measure the true obliquity of TOI-2364, a K dwarf with a sub-Saturn-mass (Mp = 0.18 MJ) transiting planet on the upper edge of the hot-Neptune desert. We used new Rossiter–McLaughlin observations gathered with the Keck Planet Finder to…

Observation and Simulation of Mutual Approximations between Five Main Uranian Satellites
Mutual approximation is an emerging method for obtaining high-precision astrometric measurements of natural satellites and asteroids. We used the 80 cm YaoAn High Precision Telescope to observe mutual approximation events of the main Uranian…
